IMPROVEMENT IN JACKS FOR BEATlNG-OUT MACHINES FOR BOOTS, &c.

Specification forming part of Letters Patent No. 155,070, dated September 15, 1874; application filed April 11, 1874.

To all whom it may concern:

Be it known that I, CHARLES W. Counts, of Marblehead, in the county of Essex and State of Massachusetts, have invented an Improved Jack for Beating-Out Machines, &c.; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention sufiicient to enable those skilled in the art to practice it.

This invention relates to the construction of a jack intended especially for use in beatingout machines, or that class of machines in which the sole of a boot or shoe is pressed to its ultimate shape, and the channel-flaps compressed against the sole after the sewing, peggin g, or nailing operation.

In my invention I form the jacks in two parts, one of which has projecting up from it the pin that holds the last, and has extending horizontally from it a tongue or tenon that enters a slot in the other part, being confined thereto by a suitable clamp-screw or other fastening, by loosening which the heel-block may be drawn out to elongate the last. The open space formed by drawing out the heelblock is filled by one or more filling-pieces, to give the last the proper support throughout itslength.

The invention consists in the jack having its heel-block made adjustable by means of a long tongue or slide projecting therefrom, and entering a dovetailed groove in the base of the toe-block, and held at any desired position by means of a screw or pin entering any one of a series of holes made in the tongue, combinin g therewith the filling pieces; also, in combining with such a jack a yielding lastpm.

The drawing represents a jack embodying my invention.

Figure 1 shows the same in plan. Fig. 2 is a side view of it. Fig. 3 is a sectional elevation. Fig. 4 shows one of the fillers in elevation.

a denotes the main block, formed of metal, and having a recess, 1), for supporting the fore partof the last. 0 denotes the heel-block. This block is made with the long tongue or tenon d, sliding in a dovetail mortise, e, in the block a, and held in position by a screw, f, which, passing through the block, enters some one of a series of holes, 9, in the tenon.

By drawing out or pressing in the slide the jack may be adjusted in length to the size of the boots or shoes to be operated, upon, the filler or fillers h being inserted between the blocks, to keep up its solidity, whatever may be its length.

i denotes the heel-pin that enters the hole in the last. This pin is supported upon a spring, 70, so that for different lasts the pin may yield.

The blocks are preferably made of iron, and together form a solid stand to support the shoe under the pressure of the mold or die that beats out the sole.

I claim 1. In a beatingout jack, in combination with the solid metallic main block a, the heelblock 0, provided with the long tongue or tenon projection 01, adapted and fitted to slide in the dovetailed groove 0 in the base of block a, and having a screw, f, adapted to enter any of the series of holes in the tenon to hold the adjustable heel-block to any desired position.

2. 1n combination with the blocks, the filler or fillers h, substantially as shown and described.

3. In combination with the blocks,the yielding last-pin i, substantially as shown and described.

Executed this 28th day of February, A. l). 1874.
